Answer 1

I solve it and post answer as it will may help some one

Problem :
I have below code in supportedInterfaceOrientationsForWindow.

- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
    // Suport only portrait mode for home screen
    if([self.navigationController.topViewController isKindOfClass:[ViewHome class]])

    {
        return UIInterfaceOrientationMaskPortrait;
    }
    return UIInterfaceOrientationMaskAll;
}

But delegate method supportedInterfaceOrientationsForWindow not called when use popToRootViewControllerAnimated method when there ismore then two view Cotnrollersexists in stack.

Solution :
Step1: Create sub class of Navigation controller.

Step2: Override method popToRootViewControllerAnimated and write code as below // Overwrite super class method popToRootViewControllerAnimated.

-(NSArray*)popToRootViewControllerAnimated:(BOOL)animated
{
    // Only for iOS8 and above
    if (floor(NSFoundationVersionNumber) > NSFoundationVersionNumber_iOS_7_1)
    {
        // Array which will contaimn all poped view controllers object.
        NSMutableArray *popedControllersArray = [[NSMutableArray alloc] init];

        // Tmp created controllers object
        NSArray *controllers;

        // Hold first view cotnrollers.
        UIViewController *firstViewController = [self.viewControllers objectAtIndex:1];

        // Pop to first view controllers with no animation.
        controllers = [super popToViewController:firstViewController animated:NO];

        // Add poped view cotnrollers objects to the array.
        [popedControllersArray addObjectsFromArray:controllers];

        // Pop to root view controller with animation
        [super popViewControllerAnimated:YES];

        // Add first view controller object as it is poped by above line.
        [popedControllersArray addObject:firstViewController];

        // return poped view controllers object.
        return popedControllersArray;
    }
    else
    {
        // Called super view popToRootViewControllerAnimated method and return popped
        // view controllers array.
        return [super popToRootViewControllerAnimated:animated];
    }
}
